The Merit-based Incentive Payment System (MIPS) scores providers 0–100 across four performance categories: Quality, Cost, Promoting Interoperability, and Improvement Activities, weighted under 42 CFR §414.1380. Reporting is voluntary for many small practices, so absence of a MIPS score is not a quality signal.

Board certification through an ABMS or AOA member board signals voluntary post-licensure examination plus continuous Maintenance of Certification cycles. Verify any individual provider's status through certificationmatters.org (ABMS) or osteopathic.org (AOA).

HANAN FAHMY, M.D., ED. M, FASN appears in the CMS NPPES registry as a Nephrology Physician provider holding M.D., ED. M, FASN credentials at 2001 N MACARTHUR BLVD STE 335, IRVING, TX, 75061, with a listed phone of (214) 716-7573. NPI 1659387413 was issued on 08/01/2006.

Medicare Part D records for calendar year 2023 show 219 prescription claims written by this provider, covering 28 Medicare beneficiaries and totaling roughly $39K in drug spend, split 30% brand-name and 70% generic by claim count.

Important: PlainDoctor is a directory of publicly available government data, not medical advice, a malpractice database, or a quality rating. Inclusion here does not imply a recommendation, and absence of complaints or sanctions on this page does not mean none exist — always verify credentials through the NPPES NPI Registry, your state medical board, and the ABMS or AOA before making healthcare decisions.
